Outfielder Albert Almora Jr. rejoined the Cubs last September after a five-week stint at Iowa, and his heady baserunning in Game 7 contributed to the franchise's first World Series title since 1908.

The Cubs dipped into Iowa's roster Friday when they called up pitchers Rob Zastryzny and Felix Pena to replace injured Jon Lester and Justin Grimm.

Here's a list of candidates from Iowa for a promotion:

The 2020 season marks the last year of Theo Epstein’s current World Series window for the Cubs. Here’s what the starting lineup and rotation could look like.

Rob Zastryzny, LHP: Zastryzny, who was optioned back to Iowa on Sunday with Koji Uehara coming off the disabled list, provided a big lift last August and September and can start as well as relieve.

Dillon Maples, RHP: Maples could be the organization's pitcher of the year. He has been a revelation after five disappointing seasons in the minors that followed a $2.5 million bonus to keep the 2011 14th-round pick from attending North Carolina. A team official marveled over his corner-to-corner slider that "buckles" many hitters and complements his high-90s fastball.

Matt Carasiti, RHP: Acquired in late June from the Rockies for left-hander Zac Rosscup, Carasiti possesses a 96 mph fastball. He posted a 9.19 ERA in 19 major-league appearances last season but allowed no runs on two hits in his final eight appearances with the Rockies.

Victor Caratini, C: Experience is the only factor lacking for Caratini, a switch hitter who has impressed in two major-league stints over the last seven weeks.

Jacob Hannemann, OF: The former BYU football recruit would give the Cubs a speedster off the bench.

Taylor Davis, C-INF: His chances looked promising until the Cubs claimed Rene Rivera on waivers Saturday from the Mets. Davis, who signed in 2011 as an undrafted free agent, has been a favorite the last two spring trainings and has worked with many of the Cubs pitchers.

Eddie Butler, RHP: Butler could provide the Cubs with an emergency starter from the right side, although he has been on the disabled list since Aug. 6. Butler was 4-3 with a 3.86 ERA in 11 major-league starts this year but pitched six innings only once.

The Cubs' 40-man roster is full, so they would need to clear space if Maples, Carasiti or Davis is added.
